Subject: [PATCH v11 2/9] fixup: Fix errors in modes that don't support migration
Date: Fri,  7 Feb 2025 02:07:17 +0100	[thread overview]
Message-ID: <20250207010724.3121569-3-sbrivio@redhat.com> (raw)
In-Reply-To: <20250207010724.3121569-1-sbrivio@redhat.com>

From: David Gibson <david@gibson.dropbear.id.au>

Migration is only supported in vhost user mode.  But, we need to initialise
c->device_state_fd to -1 even in modes without migration so that
migrate_handler() knows it doesn't have anything to do.
